Present Simple For Future
The Present Simple can be used to talk about scheduled future events, often related to timetables. We used the present simple as the event is considered "fixed" and unlikely to change time/place.
My train leaves at 7pm tomorrow and I arrive in Toronto at 9pm.
Note: Only use the Present Simple to talk about the future for this type of "timetabled" events.
A contraction in English is when two words are joined together and shortened using an apostrophe. The most common use is for subjects are verbs, especially 'to be' and 'to have'.
I'm a builder.
Contractions are also used to make negatives in English, using auxiliary verbs such as "do", "be" and "have".
I don't like Mondays!
Note: Contractions are not used in short answers.
Be careful how you make the contraction. Usually, the apostrophe takes the place of the vowel.
No, we aren't. NOT
Generally, most nouns in English are regular and you simply add -s to the word.

If the word ends in a s-type sound (s/sh/z/ch, etc), you add -es to the word.

Most words ending in -y remove the 'y' and add -ies in the plural.
cherry → cherries
potatos → potatoes
child → children
